Bipolar high frequency coagulation apparatus

摘要

The apparatus comprises tongs (4) having jaw parts (1,3) whose opposite facing surfaces have lengthwise ridges on their edges. The end of the movable jaw part (1) is rounded. The end of the fixed jaw part (3) is rounded to a point and protrudes beyond the movable jaw part when closed together.The contact surface of the two jaw parts is on one or two planes whose intersecting line is parallel to the axis (7) of the tongs or is a cylinder segment. The blade of the knife in the gap between the jaws is at right angles to the axis or slopes backwards or forwards, or is sickle shaped or curved.
